thats not my point, my point is what if there are 2 cpu's under each heat sink, the sink is hot but the cpu's are not. a machine with 4 cpu's? Quadra. anyways its all just rumors and guesses and a lot of hot air started by A.I.JoeG4 said:

It just doesn't work that way. Heat always moves from the hotter body to the cooler body. Since the heat is being generated in the processor, it always moves from the processor to the heatsink, and less so from the heatsink to the processor. No matter how many heat sources you have, in a balanced (closed) system, the processor will always be hotter in use than the heatsink. Period.
The Laws of Thermodynamics have a good primer here:

Just 3 Months Left!!!!!!!
Sigh - there has to be a light at the end of the tunnel.... I just hope it is not a train!
Upgrading eMacs.... tempted to buy one for the DVD and 80 gig drive so I can back up my old mac....but this picture reminds me... to a jedi,patients is a virtue. Yadda Yadda Yadda - Where is my G5.1

Lets just hope that graphic is the inended idea for WWDC, as it is coming up quickly and no updates have been announced for the PM. Could it be a jump from 2.0 to 3.0 with no update in between, sounds very unlike motorola and intel for that matter. I just hope the prices are about the same as i will be purchasing a mid end G5 with a 20, or 23" LCD, which ever is in the mid price range as well.

It's not that simple. There is also a delay between when the heat source (CPU) and the energy travels to the measurement points. If the timing curve is miscalculated, you can end up with cooked components (because the cooling ramp up far too late) or an obnoxious oscillating effect (full blast fans when the temp starts rising faster than the fans were attempting to control, then reducing speed/shutting off when too much cooling has been applied). If the sampling points aren't chosen correctly, there won't be good enough information to get a reasonable balance across the operating range.

I can tell most of you haven't been following Apple for very long. There is no chance in hell that a 3 gig chip will ship from Apple this year. Not a snowball's chance in hell. 2.4 tops imo, but maybe not even that.
jeez...
Just buy Alienware and leave the rest of us alone! I personally like the tier structure because it provides some stability in models, unlike Dells or other PCs, where everything is so different, you really don't have a "model." You have a model number but no one really cares because they all look the same and do basically the same things. Apple on the other hand, IMO has a great idea. make a computer for each group of users. While right now that plan may not be perfect with the new eMacs faster or as fast as every other computer except PM G5s, and there not being updates in forever or a corprate machine, its a good plan, they just need to continue to tweak it.

Id have to agree with Geetar, i would be very surprised if we didnt get at least 2.6 but remember there is like 6 months after WWDC, plenty of time for 3 to come out, if it doesnt come out at WWDC that is
iMeowbot said:
Which is not relevant to the rumor, which is that the processor runs cool, but the system reports it is hot, spins up the fans, and shuts down. The rumor is false.
I'm just demonstrating the rumor is false, and you're violently agreeing with me

I'll bet you a thousand dollars that Steve's prediction of 3Gigs within 12 months does not come true. I'd love to find a way to actually make money by betting against Apple and Job's lies. This bet is contigent upon finding a suitable 3rd party to hold the money that we both can agree on.
Michael Vance said:
Quoting this for posterity. We'll see what happens in the next 2 and a half months...
He's probably right, you know; It's not apple's style, or within their power, from what I can see, to meet such a deadline as the 3ghz, and it is doubtful that they would even come close by the end of the year, at this rate..
By the way, avkills, I'm still waiting for a reply about that lightwave subject..

I will honestly hold the money for like 20 bucks or free lunch or something. Powerbooks are accepted also.
Geetar said:
A thousand dollars is too much considering 2.6GHz is possible, even if very unlikely. I would be willing to make a more gentlemanly bet of say $100 that Apple does not deliver a 2.6Ghz machine by the end of the year. Of course there is still the issue of who holds the money.
Michael Vance said:I'd love to find a way to actually make money by betting against Apple and Job's lies.I believe the correct terminology is "forward looking statements."
Michael Vance said:
You, Sir, are a gentleman.
I'll take your wager.
Now who's going to hold the money.........? I'm none too sure about Parikh1234; I've a feeling he'd spend it on cappuccinos, Thai takeout or something.........
[Oh, yes, by the way I'm off to the Dallas Vintage Guitar Show tomorrow, and I'll be computer-less until I get back on Tuesday. Any other Macrumors members going there?]
boooo.... well, I have to retract my dual 2.0, 2.4., 2.6 rumor for NAB... source says it's not likely. Oh well. On the bright side, he says they're shooting straight for a 2.4, 2.8, and 3.0 GHz at WWDC. dunno. We'll have to see. The other tasty bit is that, apparently, there will be a move to PCI-Express graphics cards. This is good news, since all the major manufacturers are phasing out AGP. Makes it pretty much a no-brainer.
Bummer to have to wait, but I can't afford to buy right now anyway....

Ok Mrwheet, guess we will have to wait 2.5 months to see if you and your source are good...but its nice to think they are shooting for 3GHz and PCI-Express.
Powermac not shipping for at least 2 months
Well,
When ordering Xserve's from the AppleStore, a minimum shipping delay is noted from about 5 to 7 weeks. Well, since the conference call last night, we are now sure that the only holdup for these machines is that IBM cannot produce enough G5's at 90 nm, to furfill apple's production needs. They are ramping up production, and will be ok further in this quarter. Since the new Powermac line will use the same 90nm processors, but at even higher speeds, we won't see actual rev B powermacs for at least 2 months.
The sole thing they can do (which I doubt) is announce the powermacs, and say they are not shipping until a certain date. They won't be doing that again, so I don't think that's an option.
Sooo, delay of 2 months, today 14th of april.
A simple calculating leads us to right about... WWDC (approximately)
So my estimated guess is we will have powermac updates at WWDC, and then they will be ramping up the production at ibm a little bit further, to be able to announce G5 laptops at MSWF or an event at a related date.
Don't know about you, but i'm waiting for WWDC, rev B, here I come

NOoooo not MSWF for G5PBs...surely the lower clocked chips are more plentiful for exactly the PBs (given what other have said about how things are manufactured). Damn.
aswitcher said:NOoooo not MSWF for G5PBs...surely the lower clocked chips are more plentiful for exactly the PBs (given what other have said about how things are manufactured). Damn.
They won't use the lower clocked 970 processor, which is currently in the lower models of the powermac, because the 90nm needs far more less energy, and produces less heat. So the 970 processor is no option.
The only thing that could happen is that IBM is only having problems producing 90 nm processors > 2 ghz, and they have a separate production line for lower clocked 90 nm processors (1,5-1,8), which isn't having the above mentioned problems.
Sorry to burst your bubble..
